In common usage, most people use the word statistic to refer to research figures and calculations, either from information based on a sample or an entire population. Statistics means different things to different people.
The best way to see the Hollywood Sign is to drive up Beachwood Drive (north of Hollywood Boulevard). The Sign is clearly visible most the way up Beachwood, although the hills begin to obscure the view of the Sign near the top of the drive.
The views from Griffith Observatory are the other main draw. If you want a great view of the Hollywood sign and Los Angeles, this is the spot. In addition to the Hollywood sign and Los Angeles skyline, you can see Santa Monica and the Pacific Ocean.
